Anti-TMEM209 antibodies are used in the immunodetection of the protein transmembrane protein 209. In humans, the canonical protein has a reported length of 561 amino acid residues and a mass of 62.9 kDa. Its subcellular localization is in the membrane. Up to 4 different isoforms have been reported for this protein. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include testicular tissue protein Li 202. TMEM209 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TMEM209 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
